My Sony KP53S35 rear projection TV has a very dim picture and I was told that I need to clean the mirrors. Can you tell me how to take apart the TV to get to the mirrors and how to clean them?

Not the screen so much as the projection mirror which is located on the rear wall of the Set. If the mirror gets dull it can make the picture dim and dull looking. Cleaning the mirror will help. Some models have a small mirror which projects the image back onto the rear mirror. Dont use windex, just a damp cloth then dry good.

Other than a circuit problem it may be dirt or dust on the lens. The model indicated has 3 picture tubes.

If you unplug set and remove back cover you should be able to see and reach the large black lens dead center and above the circuit boards. If the lens are very dirty the picture will be dark and dull looking.

There is also at inside top back of set a mirror--if it is dusty or has grime on it, same thing--not as easy to get at but with back off you can use a small mirror to examine it.

Clean the lens with a lens cloth or a paper towel with glass cleaner sprayed on the towel.

With back off, 2 minute job and if picture now much brighter, you are in business. Lens, depending on how much dust etc in your area should be cleaned one time a year or more-----do it yourself job and easy.

If this told you something you did not know, rate this solution as very helpful as I do this here for free.

You should not attempt to clean the mirrors on the Sony TV because that can damage the picture quality.

Hi,
Your TV requires service and cleaning of screen, mirror and 3 lenses (of CRTs) as looks dusty.
Below is an exploded view how to take off front beznet assembly of this TV to clean inside with moist cotton cloth.
Unplug TV before taking off front of TV.

to clean the mirrors you must remove the screen first there are several screws in the back to remove the screen. then there is a mirror shaped like a polligon clean this with a dry cloth do not use a paper towel. soft colth must be used on any optical surface. then clean the optical engine lens in the same manner. them the large mirror in the back. remeber if you leave a defect on any of these surfaces it will be amplified by the screen. this system relies on a lamp to provide bright picture so replace that as well. this should be a part of your anual cleaning agreement of the after market warranty you purchased assuming you bought one. dim picture = lamp, fuzzy, dim, dull picture = dust

Your CRT coolant needs to be changed. Thats whats giving you the dim picture. You can also clean the projection mirror on the inside this often helps. But the coolant will need to be changed to get back the bright crisp picture. Hope this helps.

The important thing here is cleaning the refelective mirror inside you tv .We have noticed in dirty areas the dirt on mirror makes blurry picture.THerefore you have to open back cover and than tp cover to clean mirror and also dont forget to claen c.r.t lenses ,sisnce they are mounted facing upward ,lot of dust sit on c.r.t lens there fore clean 3 of them r.g.b..And you will notice on picture diffrence.

try cleaning mirror and lens inside

You will need to replace the "HA" board wich is the control panel and remote reciever (wich has failed). Here is a link to the part number and where to purchase from. http://www.partstore.com/Part/Sony/Sony/KP53S35/Sony/Sony/A1372288A/New.aspx
